Protection of steel members of headworks from corrosion

Shikhaliev, Yu. Z. / Poletaev, L. N.

Conclusions 1. Corrosion of the inside surfaces of pressure conduits leads to substantial head losses and to wear of these structures. During design and operation of these expensive objects, it is necessary to take measures to protect them from corrosion. 2. The inside surface of pressure conduits and surge towers can be successfully protected by means of cathodic protection. The following protective current densities are recommended: 2.75–3.5 mA/dm2 for the power conduits and 2.25–3.0 to 3.25–4.0 mA/dm2 for surge towers. 3. Tests of cathodic protection on actual objects of headworks show the possibility of its periodic connection.
